Description

  The present invention relates to a transfer device and a transfer method used for transferring a person who needs transfer care (hereinafter referred to as a transferee).

  2. Description of the Related Art Conventionally, transfer devices that support transfer operations from a bed to a wheelchair or from a wheelchair to a toilet have been proposed for transferees who cannot move by themselves due to obstacles, illness, aging, and the like. Patent Document 1 discloses a transfer device having a holder that holds a trunk of a transferee. In this transfer device, the trunk is held by a holding tool, and after the holding tool is tilted forward, the transferee is lifted by the lifting mechanism.

JP-A-6-225909

  In a transfer device that transfers a transferee in a forward leaning posture, when the transferee is put in a forward leaning posture, the transferee needs to be lifted at least so that the hip portion of the transferee is separated from the seating surface. This is because if the buttock is not separated from the seat surface when the occupant is lifted to a forward tilted position using the device, the occupant may slip off the seat surface when the orientation or position of the device is changed. Because there is.

  However, when the transferee is lifted by the apparatus, when the transferee is displaced from the holder, a situation has occurred in which the buttocks of the transferee cannot be separated from the seat surface. Among the reasons for deviating from the holder during the lifting by the apparatus, the present inventor has focused on the cause caused by the posture of the transferred person when fixed to the holder.

  Due to disability as a sequelae, muscular weakness that comes from the elderly, etc., the posture when fixed to many holders of transferees who need transfer care becomes stooped. Before the liftee is lifted, the transferee is fixed to the holder (or clings to the holder) in a stooped state where the spine is not fully extended.

  In this way, if you try to lift the transferee in a bent posture from the waist to the back, it will begin to stretch from the waist to the back as soon as the lift starts, and the hips will not move away from the seat until the back is fully extended. The buttock begins to rise for the first time. While the posture which bent from the waist to the back of the transferred person is extended, the contact position between the lower end portion of the holder and the transferred person is shifted.

  Even when the transferee is displaced from the holder, if the user tries to move the buttocks of the transferee away from the seating surface, the length of the arm to which the holder is fixed may be increased or the movable range of the arm may be increased. Although it is conceivable, the apparatus itself becomes large, and installation and handling become inconvenient.

  Further, when the transferee is displaced from the holder, the transferee's part that is in contact with the holder is different from the appropriate position, so that a strong discomfort (pain and breathlessness) is given to the transferee.

  The present invention has been made against the background of such circumstances, and an object of the present invention is to provide a transfer apparatus and a transfer method capable of preventing a transferee from being displaced from a holder.

  The transfer device according to the first aspect of the present invention faces the front side of the transferee's torso and maintains the vertical position of the holding tool that holds the transferee and the lower end of the holder. Thus, the apparatus is provided with extending means for extending the back muscle of the transferred person by displacing the holder, and lifting means for lifting the transferred person in a state where the back muscle of the transferred person is extended by the extending means. In this way, since the back of the transferee can be stretched and lifted while maintaining the vertical position of the lower end of the holder, the contact position between the lower end of the holder and the transferee does not shift, and the Does not cause discomfort to transferees.

  The transfer device according to a second aspect of the present invention is characterized in that, in the transfer device, the extension means inclines the holder.

  In the transfer device according to a third aspect of the present invention, in the transfer device described above, the holder has an upper holder facing the chest of the transferee and a lower holder facing the abdomen, and the stretching The means is characterized by moving the upper holder upward while maintaining the vertical position of the lower holder.

At this time, the lower end portion of the front holder 16a comes into contact with the vicinity of the base of the transferred person's thigh.

  Thereafter, the first arm 13 is rotated about the first rotation shaft 12. Thereby, the transferee in the state where the back muscles are extended can be lifted. As described above, after the transferee is fixed to the upper holding tool 21c, the upper holder 21c is slid to extend the holding tool 21 as a whole, so that the back muscle of the transferee can be extended. Thereby, it is possible to reliably separate the buttock of the transferred person from the seating surface without depending on the boarding posture of the transferred person. In addition, the contact position between the lower end portion of the holder and the transferred person does not shift, so that the transferred person is not given discomfort such as pain.

  In addition, in the example shown in FIG. 4, although the support | pillar 11 is installed on the floor surface, you may install on the base provided with the wheel etc. The driving of each part such as the linear motion shaft and the rotation shaft may be electric using a motor or the like, or may be manual.

Other embodiments.
FIG. 7 shows another configuration of the transfer apparatus according to the first embodiment. The transfer apparatus 10A shown in FIG. 7 has a serial link mechanism having at least three degrees of freedom. In the example illustrated in FIG. 7, it is assumed that an n-degree-of-freedom serial link mechanism is provided and an n-th rotation shaft 17 (n> 2) is provided. The transfer device 10 </ b> A includes a column 11, a first rotating shaft 12, a first arm 13, a holder 16, an nth rotating shaft 17, and an nth arm 18.

  A first arm 13 is connected to the support 11 via a first rotating shaft 12. Between the first arm 13 and the n-th rotation shaft 17, a serial link mechanism including a rotation shaft, an arm and the like (not shown) is provided. An nth arm 18 is connected to the nth rotation shaft 17.

  A front holding tool 16 a is fixed to the n-th arm 18. The holder 16 can be rotated about the virtual center 19 by driving each rotation axis constituting the serial link mechanism in conjunction with each other. Thereby, the holder 16 can be inclined and the back muscle of the transferee can be extended. The virtual center 19 is disposed in the vicinity of the lower end portion of the front holder 16a.

  Therefore, as shown in FIG. 8, the vertical position of the lower end of the front holder 16a does not change substantially even when the holder 16 is tilted. Accordingly, the lower end portion of the front holder 16a contacts the vicinity of the base of the transferred person's thigh over the front and rear of the inclination. Thereby, an uncomfortable feeling is not given to a transferee.

  The transferred person can be lifted by rotating the first arm 13 around the first arm 13. Similar to the first embodiment, the example shown in FIG. 7 can also reliably move the buttock of the transferee from the seating surface without depending on the boarding posture of the transferee.

  FIG. 9 shows another configuration of the transfer apparatus according to the second embodiment. A transfer device 20 </ b> A shown in FIG. 9 includes a support 11, a first rotating shaft 12, a first arm 13, a holder 21, a first linear motion shaft 23, and a second linear motion shaft 24. As in the second embodiment, the front holder 21a of the holder 21 has an upper holder 21c and a lower holder 21d.

  One end of a first arm 13 is rotatably connected to the support 11 via a first rotating shaft 12. One end of the first linear motion shaft 23 is connected to the other end of the first arm 13. An upper holder 21 c is connected to the other end of the first linear motion shaft 23. The first linear motion shaft 23 can extend in a direction perpendicular to the floor surface. Therefore, the upper holder 21 c can move in the vertical direction along the first linear movement shaft 23.

  A second linear movement shaft 24 is provided between the upper holder 21c and the lower holder 21d. The lower holder 21d is provided to be movable with respect to the upper holder 21c along the second linear movement shaft 24. The second linear movement shaft 24 is provided in parallel with the direction in which the surface of the front holder 21a facing the transferred person extends. By extending the second linear motion shaft 24, the lower holder 21 d moves downward along the second linear motion shaft 24.

  In the example shown in FIG. 9, the upper holder 21c is moved upward by the first linear movement shaft 23, and the lower holder 21d is moved downward. Thereby, a back muscle of a transferee can be extended. Further, the vertical position of the lower end of the lower holder 21d is not substantially changed. For this reason, as shown in FIG. 10, even if the upper holder 21c and the lower holder 21d move, the lower end portion of the lower holder 21d comes into contact with the vicinity of the base of the transferred person's thigh. Thereby, an uncomfortable feeling is not given to a transferee.

  The transferred person can be lifted by rotating the first arm 13 around the first arm 13. Similarly to the first embodiment, the example shown in FIG. 9 can reliably separate the buttock of the transferred person from the seating surface without depending on the boarding posture of the transferred person.

  In the transfer device shown in FIG. 9, after the upper holder 21c is moved upward by the first linear movement shaft 23, the lower holder 21d is moved downward to cover the lower end of the lower holder 21d. You may make it contact the transferer's thigh base vicinity. Thereby, a transferee's buttocks can be separated from a seat surface, without giving a discomfort to a transferee. In this case, since the first linear motion shaft 23 and the second linear motion shaft 24 can be driven serially, each can be driven by one drive circuit.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
